Public Transport Service

Public transport has become one of the major transport options, especially when it comes to reducing motorized individual transport and achieving sustainability while reducing emissions, noise and so on. The use of public transport data has evolved and rapidly improved over the past decades. Indeed, the availability of data from different sources, coupled with advances in analytical and predictive approaches, has contributed to increased attention being paid to the exploitation of available data to improve public transport service. In this paper, we review the current state of the art of public transport data sources. More precisely, we summarize and analyze the potential and challenges of the main data sources. In addition, we show the complementary aspects of these data sources and how to merge them to broaden their contributions and face their challenges. This is complemented by an information management framework to enhance the use of data sources. Specifically, we seek to bridge the gap between traditional data sources and recent ones, present a unified overview of them and show how they can all leverage recent advances in data-driven methods and how they can help achieve a balance between transit service and passenger behavior.

Paper deals with the use of aircraft sensors to obtain meteorological parameters required for predictive weather models, using parameters in ATM and meteorological research. It focuses on the current state of the problem of data acquisition, using the AMDAR system. Comparative use of data from other data sources such as Mode S EHS and Mode S MRAR. By building the necessary infrastructure or equipping of commercial aircraft. Within the paper is developed a methodology, which deals with obtaining data from LPS SR š.p., necessary for the comparison of different systems. The impact of the AMDAR system on aircraft instruments and on the safety of air traffic. Based on the analyzed facts, examples of the use of the system are pointed out, but also of the problems associated with this system.

The article presents the results of the analysis of health, working conditions and prevalence of adverse production factors, the structure of the detected occupational pathology in the working population of the Russian Federation. The article presents Statistical data on the dynamics of the share of workplaces of industrial enterprises that do not meet hygienic standards, occupational morbidity in 2015-2018 for the main groups of adverse factors of the production environment and the labor process. The indicators of occupational morbidity over the past 6 years in the context of the main types of economic activity, individual subjects of the Russian Federation, classes of working conditions, levels of specialized occupational health care. The role of the research Institute of occupational pathology and occupational pathology centers in solving organizational, methodological and practical tasks for the detection, treatment, rehabilitation and prevention of occupational diseases is shown. The basic directions of activity in the field of preservation and strengthening of health of workers, and also safety at a workplace are defined.

STEAM is an acronym for Science, Technology, Engineering, Art, Mathematics. STEAM defined as the integration of science, technology, engineering, art, and mathematics into a new cross-disciplinary subject in schools. The concept of integrating subjects in Indonesian schools, generally is not new and has not been very successful in the past. Some people consider STEAM as an opportunity while others view it as having problems. Fenny Roshayanti is science educator and researcher that consider STEAM as an opportunity. She has involved the study of STEAM, as an author, educator, academic advisor, and seminar speaker. This article examines what it has been and continues work from Fenny Roshayanti in the science education. Our exploration uses qualitative methods of narrative approaches in the form of biographical studies. Participants as data sources were selected using a purposive sampling technique which was collected based on retrospective interview and naturalistic observation. Data's validity, reliability, and objectivity checked by using external audit techniques. This work explores the powerful of female’s personal style in developing a form of social influence based on her forms of capital as well as address the positive and negative consequences that may follow while implement and research STEAM in teaching classroom.
